Translation of nad9 mRNAs in mitochondria from Solanum tuberosum is restricted to completely edited transcripts.
Article in Nucleic acids research, 1994. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The pool of partially and completely edited mRNAs present in plant mitochondria could potentially be translated into a mixture of divergent proteins. This possibility was investigated for the nad9 gene in potato by characterization of the mRNA population and the corresponding protein sequence. The deduced amino acid sequence of the nad9 gene product has significant similarity to the nuclear-encoded 30 kDa subunit of the bovine and Neurospora NADH:ubiquinone oxidoreductase (complex I) and to the chloroplast ndhJ gene product. Immunoprecipitation of a 27 kDa in-organello 35S labelled mitochondrial translation product with an antibody directed against the wheat nad9 gene product demonstrates its functional expression in potato and wheat. Comparison of the nad9 genomic DNA and cDNA sequences reveals seven codons to be changed by a C to U RNA-editing. Direct sequencing of RT-PCR products derived from cDNAs of different tissues of potato plants shows the presence of a significant portion of only partially edited nad9 transcripts in the various tissues. Amino acid sequencing of internal peptides of the isolated 27 kDa protein from potato tubers demonstrates homogenous translation products of only completely edited nad9 mRNAs even in the presence of partially edited mRNAs. This result suggests a pretranslational selection between edited and incompletely edited mRNAs in plant mitochondria.
